Configuration for Nginx Proxy

If you are using a Nginx server that supports .htaccess rules, but you still have a server configuration error on the plugin settings page, additional Nginx server configuration is required for the Xilifox Image Optimizer plugin to work properly. This indicates a problem with Nginx Reverse Proxy for static files or Nginx Caching for static files.

• Step 1.#

  Start an SSH connection to your website or forward this instruction to your server administrator.

• Step 2.#

  Find the configuration file in one of the paths (remember to select configuration file used by your domain):

  • /etc/nginx/sites-available/ or /etc/nginx/sites-enabled/
  • /etc/nginx/conf.d/

• Step 3.#

  Check if you have similar rules in your configuration file for your domain (the list of extensions in the location directive may vary, so look for similarities):

  location ~* ^.+.(css|js|jpg|jpeg|png|gif|webp|ico|eot|otf|woff|woff2|ttf)$ {
    expires max;
    ...

  or

  location ~* ^.+.(css|js|jpe?g|png|gif|webp|ico|eot|otf|woff|woff2|ttf)$ {
    expires 1M;
    try_files $uri @proxy;
    ...

  Depending on the configuration, these rules may be located in a different configuration file if the configuration is divided into several files.

  If you find such rules, please remove the following formats from the location directive:

  • jpg and jpeg or jpe?g
  • png
  • gif
  • webp

  This is what an example location directive looks like before the change:

  

  This is what the same directive looks like after the change:

  

• Step 4.#

  Restart the Nginx server using the command:

  systemctl restart nginx

• Step 5.#

  That’s all! Our plugin will work properly.
